In the embodiment of theinvention as disclosed in the several drawings it will be seen that the invention includes a series of instrumentalities arranged successively from right to left in the drawings. -As here shown the right hand end of the machine will be referred to in what follows as the rear or feeding end and the left hand end of v the machine will be termed the delivery: or front end of the machine. Also, the side of the machine-seen in Figures 2a and 2b will be termed the right side of the machine, the opposite side being, of course, termed the left side.

. At the rear of the machine is located a yarn supply means indicated in general at A. The remainder of the mechanism has a frame structure common to substantially all of the other features except certain auxiliary. apparatus such as pumps, tanks and pipe connections therefor. At the rear of the main frame is arranged a yarn tensioning and feeding device indicated in general 'at B. This feeds the yarn to a dyeing and treating apparatus indicating in general at C from whence the yarn passes to a preliminary dryer indicated in generalat D.

v In the yarn-supply means shown ,at A thereis provided a pair of frame orcree1 sides Ill adapted to revolubly support a series of drums or beams ll having the yarn to be dyed wound thereon, these beams being preferably of standard width. The creel is so designed that the yarns from the different beams may be doubled together in unwinding to have the several yarns lie side by side to form a flat sheet or a tape depending on the number and arrangement of 'the beams. If desired a scallop board (not shown) may be used to assist in thetaping operation;

At the rear of the main portion of the machine is a pair of brackets is on each of which is mounted a set of three bearings 20 wherein are liournalled three feed rollers 2|. At the left side of the machine these rollers have their journals 22 provided with meshi diameter so that rollers aregeared together to revolve 'at equalflfpeeds- On the journal not one of these rollers is fixed a'bevel gear 24 wherewith meshes a bevel gear I! fixed on a shaft 26.

The supports and drive for this shaft will be described hereinafter but it is to be now understood that, during the operation of the machine thegears :21 of equal pitch shaft 26 is constantly rotated. Pivoted to each of the brackets I8 is a depending tension roll arm 21 and in the lower ends of these arms are revolubly mounted the'journals 28 of a tension roll.

29. To each arm 21 is connected the rear end of a forwardly extending tension spring to which has its forward end anchored to the bracket I! so that the tensionroll is constantly urged for- The dyeing and treating apparatus The apparatus indicated at C includes a vat or tank 33 extending longitudinally of themachine and supported on bearers 34. This tank, at its rear end supports the brackets I8 and extends forwardly from these brackets. Spaced from the rear end of the tank is a transverse partition 35 which divides the tank into a rear dyeing section and a forward treating section centrally of the dyeing section is a partition 36 dividing the dyeing section into rear and forward compartments. The partition .38 is provided with a manhole which may be closed bya manhole cover 38 which may thus separate thetwo compartments or may beremoved to throw the two compartments into one. In dyeing for the darker or more pronounced shades the manhole is opened but, for lighter and more delicate shades the manhole maybe closed and the forward compartment alone used for dyeing, the rear compartment' being used, if desired, to effect a pre-.'

ards support the journals 3! of lower yarn guiding rollers 40. These rollers revolve on fixed axes. At the upper end of each standard is a bearing fork 4| and intermediate its height each standard 39 has a rcarwardly opening and downwardly directed bearing slot 42. Upper yarn guiding rollers 43 are provided with journals 44 which may be positioned either in the forks 4| or the slots 42 so that these upper rollers may be positioned above the water line of the dye bath or below this water line. The water.line thus lies between the two positions of the upper rollers. The, yarn passes around these rollers in the manner shown in Figure 15. By means of this selective positioning of the upper yarn guide roll.

era the yarn may be kept immersed during .its en compartment or may be tire travel through each caused to pass into the air above the bath any number of times within the limits of the arrang'ement (as shown from one to eight times) in order to effect dxidation of the dye when usingcertain types of dyes. The forward 34 is preferably divided into bytransverse partitions .4! and in each of the compartments thus formed there is provided a set of three pairs of bearing standards 40 carrying lower guide rollers 41 and upper guide rollers 48. The standards 48 are identical in form and function with the standards ll so that the upp r guide rollers may be positioned in the baths four compartments k me ee treatment compartments or above section of the tank (1 46 has a forkbearing slot, bearing Thus each standar 49 at its upper en 58 below the fork.

A steam main 9| supplies each of the coils 88, being connected thereto by branch pipes 92 controlled by valves 93. Below the coil 88 is a second "coil 94 having pipes which are perforated as at 95 to permit steam to fiow directly into the baths of the several compartments. The coils or heaters 94 receive live steam from a steam main 96 connected to each heater 94 by a branch pipe 91 controlled by a valve 98. By means of this arrangement the baths may be heated with-or without the mixing of live steam with such baths.

Only a portion of the drier D is shown, this drier being a steam heated cylinder or drum I89 mounted in bearings I0! which also support a guide roller I82 over which the yarn passes as shown by the broken line Y.

In starting the dyeing operation the different compartments of the vat are charged with the desired liquid and the upper guide rollers 43 and 48 are positioned in the upper or lower forks in accordance with the particular requirements of the operation. The hand wheels 69 are now manipulated to allow the arms H to rest upon the lugs 11 and thus relieve the pressure due to the weights 95. Further turning of the hand wheels in the same direction lifts the upper squeeze rolls 1| so that they are spaced from the lower rolls 58. The strands of yarn from the beams H are now assembled side by side and threaded through the machine in the manner shown in Fig. 15. The hand wheels 69 are now manipulated to squeeze the yarns between the lower and upper guide rollers by turning the hand wheels in such directhe bearings 11 downwardly and lift the arms Bl off the lugs 11. The squeeze rollers will now be urged together by the weights 65. It is to be understood that these squeeze rollers and the feed rollers2l are so geared to the shaft 26 that they have equal peripheral speeds. being started, the inertia of the beams II will render them slow to start so that, were it not for the provision of the relief roll 29, the feed rollers 2| would exert a stress 'on to break the yarn. The'roller the yarn tending 29, however, moves rearwardly at this time against the action of the springs 30 so that the stress is brought gradually on the yarns and the to rotate before the stress is sufficient to cause breakage. Also, any variation in resistance of the beams to unwinding will be compensated by movement of the roll 29 so that the tension exerted by the feed rolls 2| on the yarn will be kept substantially uniform. Since the yarn is system as'fast as it leaves the system and since all the squeeze rolls run at the same peripheral speed) the only tension exerted on the'yarnwill be that sufficient to rotate one group of guide rollers and this will be so small as to be negligible. be said to pass through the vat system in a substantially tensionless condition.

There has thus-beenprovided a simple and efficient device of the kind described and for the purpose specified.

It is obvious that minor changes may be. made in the form of construction of the invention withthe material spirit thereof. It is not, therefore, desired to confine the invention to the exact scribed, but it is desired to include all such as properly come within the scope claimed.
